Don't use sunscreen spray near an open flame or you may find yourself on fire.

That's the message from the U.S. Food and Drug Administration which received five reports last year of people doing just that and sustaining burns serious enough to warrant a trip to the hospital.

In each of the incidents the fire occurred after the sunscreen had already been applied and the victim neared an ignition source, such as a lighted match. In one case, the victim began welding after applying the sunscreen.

Though the specific products involved in the incidents were recalled, other sunscreen sprays contain a flammable ingredient such as alcohol. Sunscreen spray is not the only product to worry about. Spray insect repellants, hairspray and even non-spray sunscreens may contain a flammable ingredient.
